. l face at the upper part of the receptacle, so that when the puncturedcontainer is withdrawn, the

contained liquid will be stripped therefrom.

Such a device may be used to deliver lubricant to a receiver, such asthe crankcase of an automobile, and is intended to effect the completeemptying of the container of its entire oil contents including thatwhich would otherwise adhere to the inner walls of said container, orwhich would be slow in reaching the outlet of said container.

One object of the present invention is to provide a new and improveddevice of the general type referred to.

Another object is to provide a device of the 25 general type referredto, having means for guarding the puncturing member so as to preventaccidental hand contact therewith and resultant injury to the operator.Another object is to provide puncturing means so for forming a drainopening of large cross-sectional area closely adjacent to or contiguouswith the bottom of the container, to insure a faster outflow of liquidfrom said container, and to prevent the forming of oil retaining pocketsin the lower portion of the container.

Still another object is to provide new and improved means for supportingthe puncturing member so that said member may be easily taken out of thereceptacle for sharpening or replacement.

A further object is to provide a device of the general type referred to,which may be easily assembled or disassembled.

Various other objects, features and advantages of the invention will beapparent from the following particular description and from aninspection of the accompanying drawing. In the drawing- Fig. 1 shows avertical section of one embodi- 5 ment of the present invention, withthe container punctured and ready to be drawn out of the receptacle withaccompanying stripping action,

and

Fig. 9 is a perspective view of the collapsed punctured bag after it hasbeen stripped of its' entire contents.

In Figs. 5-8 is shown a form of flexibly walled oil container l0 whichmay be used inconjunction with the present invention, and which is morefully disclosed and claimed in a copending application, but it must beunderstood that any other type of flexibly walled container may be usedfor the purpose of the present invention. In the form shown, the bag ismade from thin flexible sheet material in strip form, which isprogressively collapsed and sealed longitudinally at the edges andtransversely at spaced points along the length thereof, and which isthentrans versely cut intermediate of the ends of the sealed portion toform the complete hermetically sealed 'collapsed bag Ill.

The bag I0 is formed primarily of impervious flexible sheet materialwhich may be sealed by heat and pressure, or by the use of adhesives orsolvents. For instance, it may be material sold under the name ofPliofilm, which is made from a chlorinated rubber compound, and which isthermoplastic and readily vulcanized or sealed at a temperature ofapproximately 115 C., so that overlapping sections thereof may be sealedtogether by the application of heat and pressure.

The bag I0 is formed of a sheet ll of Pliofilm or other materialreferred to, having its side sections l2 heat sealed to the sides of anarrower sheet of Pliofilm I3 along its entire length to form a tube.The sheet II is tucked inwardly from a the sides of the sheet l3 to forma pair-of infolds H on each side of the collapsed bag. These infolds Hare narrow so that the inner fold edges of one pair of infolds do notabut or overlap the inner edges of the opposite pair of infolds, 55

latter edges.

Cemented or otherwise secured to the Pliofilm sheet l3 to form alaminated wall therewith, is a reenforcing sheet I! made of paper orother flexible sheet material which will not be iniuriously affectedby-the application of sufficient heat and pressure to effect sealing,fusing or vulcanizing of the Pliofilm. In order that the comer of thebag l0 along. the side edges of the sheet I! be strong when in fullycharged condition, said sheet it extends beyond the side edges of thePliofilm sheet i3 to form marginal extensions l3, and portions of theside sections l2 of the Plioflhn sheet II project outwardly beyond theside edges of said sheet l3, and are directly glued or cemented at A tosaid marginal extensions. Such sealing by adhesive and byattachment ofthe sheet it directly to the paper sheet i5 at the corners, has areenforcing effect which will compensate for any weakening resultingfrom heating and softening of the Pliofilm at the comers.

In the forming of the bag, the continuous tube in collapsed condition issealed transversely thereacross over an area whichis then transverselysevered, so that the portion of the sealed area on one side of the lineof severance forms the bottom seal across the entire width of the bag l0as shown in Fig. 8, while the portion of the sealed area on the otherside of the line of severance forms the side seals 2| in the top of thenext succeeding bag, the portion of said latter bag between said sideseals 2i forming an opening through which the latter bag may be filled.

After the bag has been filled, the opening thereof is permanently sealedby heat-sealing together the facing Pliofilm linings of said opening.The sealing across the tube is eifected by heat and pressure so that allof the superposed layers of Pliofllm are autogenously bonded togetherand to the sheet l3. The bottom seal 20 will consist of two thicknessesof Pliofilm sealed together at the center, and seven thicknesses ofPliofilm sealed at the side edges.

Since the sealing across the tube is eflected by a single heat-sealingoperation, non-uniformity in the number of overlapping Pliofllms acrossthe width of the collapsed tube might, un-

der some circumstances, cause the overheating of the center portion ofthe tube whereby the overheated section of the Pliofilm sheet ll alongsaid center portion might stick to the platen member forming part of thesealing apparatus. In order to avoid the liability of this happening, apaper sheet 22 may be cemented or otherwise secured tothe Pliofilm sheetI 1 across an area extending slightly beyond the inner edges of the sideseals.

The two paper sheets I 5 and 22 on opposite sides of the container servenot only for the purpose referred to but may also serve to carryadvertising or other printed notices.

The container of Fig. 6 has a capacity which is greater than the amountof oil stored therein so as to compensate for the change in volume ofoil due to changes in the temperature thereof. The air from the headspace above the liquid level is exhausted so that the opposite walls ofthe upper portion of the container may come together as shown in Fig. 6to form a comparatively long "flap 23.

The containers asshown in Fig. 6 lend themselves to efilcient storageand transportation in trays of the multiple compartment type. If thecompartments of these trays be of such size as but are spaced'asubstantial distance from said to snugly receive one of said containers,the sediment or other foreign material collecting in the bottom cornersof the compartment might, under some circumstances, puncture thecontainer and cause leakage thereof. In order to avoid this possibility,the paper strip 22 extends beyond the cuter edges of the infolds l4, sothat when the container is placedin a tray compartment with the paperstrip 22 facing downwardly, the marginal extensions 24 of said strip 22beyond said infolds will fold upwardly along the side walls formed bysaid infolds i4 and thereby protect the bottom corners of the bag fromdirect contact with foreign matter which may have collected in thecorners of the tray compartment.

In the specific embodiment of the invention shown in Figs. 1-3, there isprovided a receptacle which is so designed as to receive a suitableflexibly walled container in upright position. in the specific formshown, the receptacle comprises a tubular'sheli ll of rectangularcross-section having a front wall 32, a rear wall 33 and side walls 34.The bottom of the receptacle may be formed by a plate 35 connected tothe tubular shell 3| by any suitable means, as for instance soldering,and having a'substantially horizontal section 31 spaced from the bottomof the tubular member 3|, and an oblique section 38 extending to thefront wall 32. This oblique section 38 is provided with an opening 40and has a discharge nozzle 4! connected thereto in communication withsaid opening. A flexible hose 42 may be connected to the nozzle 4i, andpasses through the front wall 32, and its delivery end is adapted to beinserted in the inlet of a lubricant receiver to be filled. The end ofsaid hose may be provided with a hook (not shown) for engaging a staple43 connected to the front wall 32 so that said hose may be supportedclose to the receptacle in non-dripping position when not in use.

The bottom wall 'section 31 slants slightly downwardly towards thenozzle 4i so that the oil collected in the bottom of the receptacle willflow towards said nozzle.

Extending between the side walls 34 f the receptacle and spaced inwardlyfrom the rear wall 33 is a plate 45 servingto form the rear wall of thecontainer receiving chamber 46 of the receptacle and forming with saidwall 33 a compartment 41 for receiving at least a portion of thestripper operating mechanism. This plate 45 is detachably secured withinthe shell 3| in any suitable manner. For instance it may be providedwith a pair of side flanges 48 extending along the side walls 34 andhaving notches 50 at their bottoms for engaging buttons or studs 5|connected to said side walls 34 to hold said plate 45 against lateralmovement. At the upper ends these flanges 48 may be connected to theside walls 34 by removable fastening means such as bolts 52. V

The bottom of the plate 45 is provided with an opening 53 to afford freecommunication between the chamber 45 and the compartment 41, therebypreventing oil from being retained in said latter compartment duringcontainer discharging operations.

The puncturing member includes a knife disposed within the lower portionof the container receiving chamber 46 of the receptacle and adjacent tothe outlet opening 40. As an important feature of the present invention,this knife is constructed to form a knockout flap 54 in the bottom ofthe container so as to form a drain opening of substantialarea. For thatpurpose, this knife is of substantially U-shaped cross-section and isadapted to form a correspondingly shaped slit in the bottom of the con"-tainer. In the specific form shown, this crosssection is somewhatsemi-cylindrical and the knife 55 is provided with a pair of cuttingedges 56 converging towards a sharp piercing point 51. The bottoms 58 ofthe cutting edges 56 extend approximately along. the medial plane .ofthe container receiving chamber 46 of the receptacle so that the knife55 as it pierces the bottom of the container as shown in Fig. 6, makes aU-shaped slit 60 down to the bottom seam of the container as shown inFig. 9. This slit 60 defines a drain opening which is of substantialarea and which extends to the extreme bottom of the container, so thatno liquid retaining pockets are formed in the bottomof the container onopposite sides of said drain opening.

As an important feature of the present invention, the knife 55 issupported on the detachable wall 45 so that said knife can be taken outof the receptacle for sharpening or replacement. For that purpose thereis provided a pair of rods 62 soldered or otherwise connected at one endtothe lower section of the knife 55, and having the other ends passingthrough the wall 45 and forming angular extensions 63 soldered orotherwise connected to said wall. The bottom of the knife 55 rests onthe bottom wall 36 of the receptacle to support said knife against thepressure of the bag ill during puncturing operation.

The stripping device comprises a pair of vertically spaced platenmembers in the formof rods 65 presenting platen surfaces for cooperationwith a rotatable pressure roller 66. This pressure roller 66 is normallyurged into pressure applying position with respect to the platen rods 65as shown in Fig. 1, and is angularly movable into inoperativepositionshown dotted in Fig. 1 to permit the container ID to beinsertedbetween said pressure roller 66 and said platen rods 65. Forthat purpose, the pressure roller 66 is rotatably carried by a pair ofsimilar lever arms 61 extending closely adjacent to the side walls 34and pivoted respectively to said side walls at 68. In order to angularlymove the lever arms 61 about their pivotal connection 66, each of saidarms has an extension arm 10 passing through an opening in the plate 45and having an elongated slot 1i through which passes the end of a rod12. Fixed to the central portion of said rod 12 is one end of a leverarm 13, the other end being fixed to a rod 14 journaled in suitablebearings connected to the flanges 48 of the detachable wall plate 45.

The lever 13 is actuated by an operating mechanism in the form of athumbpiece 16 extending through a slot 11 in the rear wall 33. The depression of the thumbpiece 16 in a clockwise directionas shown in Fig. 1into the dotted position shown, causes the, rotation of the rod 14 andthe corresponding angular movement of the lever arm 13 so that the leverarm 61 carrying the pressure roller 66 is swung in a counterclockwisedirection.

In order to normally maintain the pressure roller 66 in the pressureapplying position shown in Fig. 1, there is provided a torsion spring 16encircling the rod 14 and having one end 19 curved downwardly as shownin Fig. 1 andengaging the detachable wall 45 so that said rod 14 isurged in a counterclockwise direction. Under the action of the torsionspring 16, the stripping device will normally be in the position shownin Fig. 1 and will be locked, so that the movement of the pressureroller 66 away from the platen rods 65 can be effected only by theupwardly towards the receptacle, so that the thumbpiece 16 isconveniently accessible. for operation by the thumb of the hand graspingsaid handle.

In order to provide resilient yield between the pressure roller 66 andthe platen rollers 65 dur ing stripping of the container so that saidmembers may permit the extra thickness of the container, such as thatalong the bottom seam, to pass therebetween, the platen members 65 arewelded or otherwise connected to a pair of spring plates 64 connected attheir lower ends to the detachable wall plate 45.

By means of the construction so far described, the entire strippingmechanism and the knife 55 are supported solely on the detachable plate45 and may be removed from the receptacle as a unit with said plate.

In order that the pressure roller 66 in inoperative position shown indotted lines in Fig. 1 and the platen members 65 do not interfere withthe dropping of a container in the chamber 46, the upper section 86 ofthe wall 32 and the. upper section 81 of the detachable wall plate 45are flared upwardly to form recesses to receive these members as shown.

As a feature of the present invention, means are provided for renderingthe knife 55 inaccessible for container puncturing operation while thereceptacle is not in use, so as to prevent the hand of the operator fromcoming in contact with said knife and being accidentally injured. In thespecific form shown in Fig. 1, this means is in the form of a guard 90which, when the receptacle is not in use, extends over the open end ofthe receptacle to prevent a. hand from being inserted in the interior ofthe receptacle. This guard is formed of a wire having end extensions 9|soldered or otherwise connectedto the lever arms 61 so that said guard90 is actuated in unison with said lever arms. and having anintermediate U-shaped section 92 so that when this wire guard is in thedotted position shown in Fig. 1, said U-shaped section 92 clears thenozzle retainer 43.

In the construction shown in Fig. 5, the guard serves not only toprevent the insertion of the hand into the receptacle but also serves asa cover for the receptacle so that rain or other foreign matter does notfind its way into said receptacle while it is not in use. In this formthe guard is in the form of a coverplate 94 pivotally connected to theupper end of the front wall 32 of the receptacle by a hinge 93 andhaving a sloping section 95 presenting a cam surface which is engaged bythe pressure roller 66 as it is moved in a counterclockwise direction.This riding of the pressure roller along the cam section 95 causes thecover plate 94 to swing open ina counterclockwise direction about thehinge 93 so that the upper end of the receptacle is uncovered to permita container to be dropped therein.

In order to limit the open position of the cover plate 94, said platehas an extension 91 on its hinge section, which engages the oblique wallsection 86 of the receptacle in limiting position,

to prevent further counterclockwise rotation of said cover plate 94. Inthis limiting position the cover plate 94 will be urged into the closedposition shown in Fig. 5 by its own weight.

When fllling a crankcase or any other lubricant receiver, it is quiteoften necessary to empty a number of containers into the. receptacle.order to provide a suitable and conveniently located receptacle for thecontainers as they 'are emptied, a plate I00 is connected to the bottomof one of the side walls 34 of the receptacle and is shaped to form areceptacle i0l therewith. Connected to this plate I00 and to said lastmentioned side wall 34 is a wire frame I02 forming with the receptacleIN a basket. The containers as they are emptied, are dropped into thisbasket and held therein until the operation of filling the lubricantreceiver is completed.

In the operation of the device, in order to move the guard 90 of theconstruction of Fig. 1, or the guard 94 of the construction of Fig. 5,into position to permit dropping of a container into the receptacle, thethumbpiece I6 is depressed. This operation causes the pressure roller 66to move into the dotted position shown, and said guards to move awayfrom the upper end of the receptacle- While in this position, thecontainer I0 is dropped into the chamber 48 and the piercing knife 55forms a substantially semi-circular opening closely adjacent to thebottom seam of the bag as shown in Fig. 9. The pressure on thethumbpiece I8 is then released and the pressure roller'68, under theaction of the torsion spring 18, is moved into the position shown inFigs. 1-5.

The receptacle is of such height with respect to the container that whenthe container I0 is in said receptacle, a substantial portion of thecontainer flap 23 will extend or may be held so that it extends abovethe platen members 65, so that when the pressure roller 68 returns intopressure applying position shown in Figs. 1 and 5, the upper portion ofthe container flap 23 will be, caught between said pressure roller andsaid platen members. The upper portion of the container flap 23extending above the platen mem-- bers 65 is grasped by the flngers andthe container drawn upwardly. The combined drawing action on thecontainer and the pressure action of the roller 86 causes the strippingof the container and the forcing out of its entire contents, to

leave the stripped container in approximately,

the flattened or collapsed condition shown in Fig. 9.

In Fig. 1 the parts are shown in approximately the position which theywould occupy after the bottom of the bag has been punctured, a portionof the contents has drained out, and the upper portion of the bag haspartially collapsed, but before the stripping action begins. At thisperiod in the operation, some-of the oil may have drained around intothe compartment 41 and more will flow into that compartment as the bagis pulled up through the stripping apparatus, but to simplify theillustration no oil is shown in that compartment.

Obviously various changes may be made in the details of construction andthe relative positioning of the parts without departing from the scopeof my invention.
